What term is used to describe plant and animal species exclusive to the Western Ghats and not found anywhere else?

Endemic

The correct answer is Option (1) -Endemic

The term used to describe plant and animal species that are exclusive to a particular region and not found anywhere else is "endemic."

Endemic species are unique to a specific geographic area and have evolved and adapted to that particular environment over time.

In the context of the Western Ghats, it means that there are many species of plants and animals that are found only in this mountain range in India and are not found in any other part of the world.

These endemic species are considered to be of significant importance for conservation efforts, as they contribute to the biodiversity and ecological significance of the region.
